A friend of mine came yesterday to me asking if I can do something for him to control WinAmp via a Remote Control. After some searching I found a very simple to build IR receiver using the serial port on LIRC official page so I started to gather the components from our local electronics shop. It costed me around 1.5$ so it was also cheap enough 
.
The schematic is
and the components are as follows :
- IC1 = 78L05, 5V regulator
- IC2 = TSOP1738 , IR receiver
- D1 = 1N4148
- C1 = 4.7uF
- R1 = 4.7K
- one male or female (depends on your configuration/cables) serial (DB9,RS232) connector
I choosed to put all components on air and in the serial connector’s box (photos below).
The pinouts of the 9-pins connector are :
- 1 = DCD (Carrier Detect)
- 2 = RXD (Receive Data)
- 3 = TXD (Transmit Data)
- 4 = DTR (Data Terminal Ready)
- 5 = GND (Ground)
- 6 = DSR (Data Set Ready)
- 7 = RTS (Request To Send)
- 8 = CTS (Clear To Send)
- 9 = RI (Ring Indicator)

- Girder – free trial, can be buyed for about 40$
- WinLirc if you are on Windows and Lirc if you are on an UNIX platform -freeware
- WinAmp Plugin for WinLirc
- BSPlayer – a very good video player, it have a built-in support for WinLirc
(Edited) As a remote control you can use almost all universal remote controls (you must know its working code for the TSOP1738, for the one from the attached picture the code is 081) and most of the domestic (videorecorder, tv …) remote controls. To see if one is working open WinLirc, press Reconfigure and then Raw Codes. If when you press a button on your remote control you see lots of numbers there then it means it is working.
(Edited) To add a status LED to your receiver, just make the schematic below (I tested it last week and it went ok). The disadvantage of this is that you’ll need a battery so it can run ok.
Just click the image to see it larger

can I use the TSOP 1736 and maxwell remot controle please and I need help for winlirc use
thank you a lot
Didou .. you can use TSOP 1736 without any issues instead of 1738.

They sell IR remotes for windows, just plug the receiver into the USB port and go, no drivers needed. Mine cost $12.99 at a local electronics store and it came with new batteries. I came here looking for information to hack one and use the parts to convert a dauphin keyboard into a remote. Guess I’ll have to take it apart and poke around…lol.
can i remove the diode pls help me on this???
No, the diode is for your port’s security.
thanks for your information…
instead of 4.7uF i took 10uF capacitor. after pressing keys of remote nothing is coming in hyperterminal. i checked for 1200 baud rate. please any body can help me out.
You could try with higher baud rates like 112000.
Hi, I’m very new in electronic, but I would like to know if its possible and not too difficult to make a “digital keyboard” (yeah, the ones with lasers and IR lights), I don’t need the laser part, I only want to know how to make the sensor and adjust it to recognise where’s each “key”
